As part of a central Government funding stream (The DfT’s Incentive Fund) the council is required to show commitment to long term asset management in a number of areas.
One of these areas is ensuring that our Highway network is resilient to major events. As part of this we have put together the following resilient network plan to explain how we would mitigate against the effects of heavy rainfall, flooding and snow.
Following discussion between engineers in our team based on a flood map that had been put together in 2011, we came up with the following summary points.
The following areas were highlighted as being more prone to flooding than the rest of Slough, but have not flooded recently.
Based on the above, we discussed possible re-routing plans for the Manor Park and Colnbrook areas, as follows.
With regards to mitigating the effects of increased rainfall within the areas that are prone to flooding, we discussed the following engineering good practice.
In the event of receiving a warning of severe rainfall in Slough, we would:
If a flood event does occur, we will be in contact with the relevant risk management authorities and emergency services as required.
One of the long term measures we are currently looking at is the dredging of ditches to ensure all silt and debris build up is cleared and that water can flow freely. Also, we have begun placing markers at various points in front of the screens throughout Slough to enable us to monitor a rise in the water level.
Finally, after a flooding event we would document all action taken, how effective it was and incorporate the lessons learnt into this plan.
We publish a winter maintenance plan annually, outlining carriageway routes that are salted, pedestrianised areas hand salted in the event of heavy snowfall, locations of salt bins etc. Any issues encountered during the winter season are discussed among the engineers within our team and changes are incorporated into the maintenance plan for the next year.
